| Abstract: |
| The real signal model based on polyphase filter banks an
d its advantages and disadvantages are discussed. First, for the problem o
f blind-zone and through reducing the multiple of decination, the algorithm i
s improved. Then, a mathematical model of no-blind-zone channelized receiver i
s derived. The two models are simulated respectively and the results show that b
oth the improved algorithm and the ameli
orated model are valid and practical. Adopting this improved algorithm can reali
ze total probability interception and capturing of signals. |
